How to modify communication between two internal networks? (Ethernet VLAN or just Ethernet for the type)

Sergio Salazar

Hello we have a Sophos SG210 with the following firmware 9.407-3

We are wanting to figure out where we should be going to modify the communication between two internal networks. We want them to be able to talk to each other but we want to restrict access so that they are not freely communicating with each other.

    booth is possible.

    if you have a dedicated switch for every network you do not need VLAN.

    but if you have booth networks at the same switch and isolate them with VLAN, you may use one Connection with VLAN tagged packets to connect booth VLANS to the UTM.

    check https://en.wikipedia.org/wiki/Virtual_LAN

    easiest way without using vlans:

    each network should use other ip-net (e.g. 192.168.111.0/24 and 192.168.112.0/24).

    connect them on two ethernet ports on your firewall and use routing / packet-filter easy as you want.

    Hi, Sergio, and welcome to the UTM Community!

    If the suggestions from Dirk and zaphod don't get you where you want to go, please be more specific about what restrictions you have in mind.

    Cheers - Bob
